To all cviwm it may concern:

Be it known that I, ARTHUR l5. Fewer-I, a citizen of the-United States, res ding at W'inchendon, county of Worcester, and State I of Massachusetts,

in 7V0(xi-Fleeing Machines, of

have invented an imrovement which the following description, niconnec;

tion with the accompanying i awings is a; specification, like letters on the drawings representing like parts.

The i vention to he hereinafter described relates to surface laners, and more illilltlqll larly to those surface laners iii-Which the cutter cylinder or cylindersere each driven 5 dlrectly from a motor.

There are two types of woocllaners in common use at the present time, namely, the single surfecer and the double surfccer'. The single surfacer finishes but one surface of a board or piece of timberwhile a doublesurfacer finishes both sides of the Work. A double sni facer has two cutter cylinclers the upper cylinder usually being fixed and the s lower cylinder being adjustable towerri and from the upper cylinder to accommodate work of different thicknesses and to vary'the depth of out; and. in order that work of uniform thickness may be protincecl, the two cylinders should remain parallel throughout an all positions of adjustment.

. {:The present invention contemplates the provision of direct motordrive for the cot ter cylinder or cylinlers and appropriate adjustingmeans all of which. will pasthe the following description and accompanying drawings of the pre ferred embodiment of the inyention, in whicl ze Figure l is general. View efe double sun 4e face planer emboclying the present invention; Fig. 2 is .:spective view -'i. some o certs cerriecl thereby; 3 is an eiiieigetl detail with parts in showing" more particm supporting the lower cutter cylimier endi motor; Fig. 4% is a tion on the line e e of Fig. 3; anal 5 is an encl View of one oi the motors.

The machine Sl1 3-WI}..- l1s, .Fig 1 comprises Work supporting table 4: anal e series of rolls 5 to feed. the Work. The lower cutter cylinil er 6 carries knives bye. treinof'geering 10, 11 with the feed the distance between:thefcylintlers and-the j" feed. rolls, bytwoipairs of" wedgesfthe'nlower of the slot out on an angle correspondin of one of connected by braces 3, a;

Wedges 18 are ircfcrably interposed between the wedges 13' and the sliole frame 1'1," tile weiiges l8 mounted to sliclein suitable ways 19 in which they may be niovefi by a. worm ancl screw 20,01 other suitable means, 9 I

The angular relation of the'cylinder andthe table is under control of a Weglge 24' (Fig. i)" seated in c slot "25 in thegsli e frame 1'? below the slide 15.

T Illa preferably secured to a fl te ea 35.
